Maybe you are getting frost on your chip. That's quite common for the ST8. Rolando

I had an STL11K on my AP130 but without the field flattener I wasn't pleased with my images. Now I put on my ST8 and in 2-3 second focus exposures the stars come out fine. If I bump exposure times to 1 minute then I get a frosted appearance across my image. Anyone know what's going on?

Thank you, Roland. I suspected that too because just prior the STL wasn't showing those symptoms, so I figured it had to do with the ST8.
